Introduction

Sealing food in Mylar bags and storing them in five-gallon buckets is an effective method for long-term food storage. This technique protects against spoilage, extends shelf life, and ensures food safety during emergencies. This guide covers the tools and skills needed, as well as detailed steps for proper sealing and storage.

Tools and Materials

  • Five-gallon food-grade buckets
  • Mylar bags
  • Oxygen absorbers (300cc)
  • Metal hand level
  • Electric iron or heat/vacuum sealer
  • Gamma seal lids
  • Rubber mallet
  • Baking soda
  • Permanent marker

Preparation

  1. Choose the Right Containers: Use food-grade buckets with tight-fitting lids to prevent contamination and ensure a secure seal. Gamma seal lids provide easy access.
  2. Prepare Mylar Bags: Line the buckets with Mylar bags, leaving about two inches of space at the top. This extra space allows for easy resealing and helps remove air.
  3. Add Food: Fill the Mylar bags with dry goods, leaving enough space for oxygen absorbers. For whole grains, purchase intact kernels rather than pre-milled flour to preserve nutrients.
  4. Inspect for Pests: Before sealing, inspect purchased items for pests. Freeze rice for 24-48 hours to kill existing pests, then allow it to reach room temperature to evaporate condensation before sealing.

Sealing Process

  1. Flatten the Bag: Use a metal hand level to flatten the Mylar bag against the bucket’s edge.
  2. Apply Heat: Use an electric iron or heat/vacuum sealer to seal the Mylar bag directly on the bucket’s edge. This method ensures a secure seal and prevents moisture from entering.
  3. Expel Air: Leave a small corner opening to expel air before sealing diagonally. This step is crucial for removing excess air and ensuring the food remains fresh.
  4. Insert Oxygen Absorbers: Add 5 oxygen absorbers (300cc each) into the bag to remove air and inhibit oxidation. For optimal results, use 2000cc absorbers per 5-gallon bucket.
  5. Fold and Secure: Fold the Mylar bag into the bucket and secure the lid tightly using a rubber mallet.

Labeling and Storage

  • Label Buckets: Clearly label each bucket with the contents, date of storage, and expiration date. Use a permanent marker to ensure labels are legible over time.
  • Store in Cool, Dark Places: Store buckets in a cool, dry, and dark environment to maximize longevity and prevent degradation. Avoid storing in areas with temperature fluctuations.
  • Regular Inspection: Periodically check the contents for pests, moisture, or spoilage. Rotate stored food regularly to ensure freshness.

Nutrient Preservation

Whole grains retain up to 90% of their nutrients when stored properly, unlike milled grains which lose 45% within 24 hours and up to 90% within 3 days of milling. Purchase intact kernels (wheat, beans, corn, oats) rather than pre-packaged milled products. For long-term storage, use 5-gallon buckets with Mylar bags and oxygen absorbers to maintain freshness.

Pest Control

Pest prevention is crucial for long-term food storage. Always seal containers tightly. Use baking soda or charcoal in empty buckets to neutralize odors. Regularly inspect stored items for signs of infestation. Store in cool, dark places and rotate stock using FIFO (First In, First Out) principles.

Storage Calculations

Use storage calculators to determine the appropriate quantity of food to store based on family size, shelf life expectations, and nutritional needs. This ensures you have enough food for emergencies and sustains your family’s nutritional requirements.

Additional Tips

  • Brown rice contains oils and may become rancid within ~1 year, though sensory cues (smell/taste) will indicate spoilage.
  • White rice stores significantly longer but is less nutritious.
  • Dried beans remain safe over time but may become harder to cook as they age.
  • Original plastic packaging is food-grade and suitable for short-term storage but not optimal for extended use.
  • Vacuum-sealed bags enable storing diverse bean varieties without bulk purchases.

Conclusion

Properly sealing food in Mylar bags and storing them in five-gallon buckets is a reliable method for long-term food storage. By following these steps and tips, you can ensure your food remains safe, fresh, and ready for use during emergencies.
